    cortl_logger_instance.set_descriptor(cortl_file_helper.get_descriptor());
    cortl_logger_instance.set_level(cortl::logger::logger::level::debug);
    log_place;
    log_syserror(CORTL_LOGGER_FORMAT_ERRNO_STRING.c_str());
    log_debug("message will be output in debug mode and higher");
    log_trace("message will be output in trace mode but will not be output now according to the defined logging level (debug)");
    log_info("test %s [%d]", "snprintf", 12345);

    for(int i = 0; i < 1000000; ++i)
